Abstract
A bimetallic strip for a sliding bearing having a sliding strip of an aluminum alloy which is adhered to a steel supporting strip and method of manufacture. The composition of the sliding strip is from 3 to 30% of tin; from 1 to 6% of silicon and the remainder being of aluminum and impurities, and the sliding strip has at least 95% of the silicon hard particles smaller than 3.5 microns and an aluminum grain average size of about 6 microns. The sliding strip is produced by roll casting the alloy and attaching the sliding strip to the steel supporting strip to form the bimetallic strip which is heat treated between 200° and 380° C. to obtain a metallurgical bonding between the strips; subjecting the bimetallic strip to a solubilizing process of the intermetallic compounds of the aluminum alloy by heating at 380-500° C., followed by cooling; and subjecting the bimetallic strip to a precipitation treatment at a temperature from 150° to 250° C. An interlayer can be provided between the sliding strip and support strip.
